编译时差？

Question

I have two c++ programs named example.cpp (takes two numbers and outputs their sum) in two directories: my home directory and inside a folder in var/www/myfolder .

When I run the following command g++ example.cpp (command line) in both directories the time differs. In the first case it takes 0.5sec and in the second 0.072 sec . Why so much difference??

I am using ubuntu 12.04.

我怀疑您的主目录不在您的计算机本地，因此对其进行读写可能会导致网络延迟。
